Fields Medal Winner Terence Tao Recognizing Achievement Fields Medal Winner Terence Tao theory, algebraic geometry, number theory, and com- pressed sensing, a new area of applied mathematics. Of special note is his joint work with Ben Green, a Clay Research Fellow from 2005 through 2007. In their 2004 paper, “The primes contain arbitrarily long arithmetic progressions,” the authors answered in the affirmative a long-standing conjecture that had resisted many attempts. Vinogradov settled the case of arithmetic progressions of length 3 in 1939. Since then, however, progress had stalled, and even the case of progressions of length 4 was unresolved. For this and other work, Tao was awarded the Australian Mathematical Society Medal. Terence Tao. Courtesy Reed Hutchinson/UCLA.

The citation for the award reads: The Clay Mathematics Institute hereby awards the Millennium Prize for resolution of the Poincaré conjecture to Grigoriy Perelman. The Poincaré conjecture is one of the seven Millennium Prize Problems established by CMI in 2000. The Prizes were conceived to record some of the most difficult problems with which mathematicians were grappling at the turn of the second millennium; to elevate in the consciousness of the general public the fact that in mathematics, the frontier is still open and abounds in important unsolved problems; to emphasize the importance of working towards a solution of the deepest, most difficult problems; and to recognize achievement in mathematics of historical magnitude. The award of the Millennium Prize to Dr. Perelman was made in accord with their governing rules: recommendation first by a Special Advisory Committee (Simon Donaldson, David Gabai, Mikhail Gromov, Terence Tao, and Andrew Wiles), then by the CMI Scientific Advisory Board (James Carlson, Simon Donaldson, Gregory Margulis, Richard Melrose, Yum-Tong Siu, and Andrew Wiles), with final decision by the Board of Directors (Landon T.

  • The Work of Grigory Perelman
    The work of Grigory Perelman John Lott Grigory Perelman has been awarded the Fields Medal for his contributions to geom- etry and his revolutionary insights into the analytical and geometric structure of the Ricci flow. Perelman was born in 1966 and received his doctorate from St. Petersburg State University. He quickly became renowned for his work in Riemannian geometry and Alexandrov geometry, the latter being a form of Riemannian geometry for metric spaces. Some of Perelman’s results in Alexandrov geometry are summarized in his 1994 ICM talk [20]. We state one of his results in Riemannian geometry. In a short and striking article, Perelman proved the so-called Soul Conjecture. Soul Conjecture (conjectured by Cheeger–Gromoll [2] in 1972, proved by Perelman [19] in 1994). Let M be a complete connected noncompact Riemannian manifold with nonnegative sectional curvatures. If there is a point where all of the sectional curvatures are positive then M is diffeomorphic to Euclidean space. In the 1990s, Perelman shifted the focus of his research to the Ricci flow and its applications to the geometrization of three-dimensional manifolds. In three preprints [21], [22], [23] posted on the arXiv in 2002–2003, Perelman presented proofs of the Poincaré conjecture and the geometrization conjecture. The Poincaré conjecture dates back to 1904 [24]. The version stated by Poincaré is equivalent to the following. Poincaré conjecture. A simply-connected closed (= compact boundaryless) smooth 3-dimensional manifold is diffeomorphic to the 3-sphere. Thurston’s geometrization conjecture is a far-reaching generalization of the Poin- caré conjecture. It says that any closed orientable 3-dimensional manifold can be canonically cut along 2-spheres and 2-tori into “geometric pieces” [27].

  • The Materiality & Ontology of Digital Subjectivity
    THE MATERIALITY & ONTOLOGY OF DIGITAL SUBJECTIVITY: GRIGORI “GRISHA” PERELMAN AS A CASE STUDY IN DIGITAL SUBJECTIVITY A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Arts in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, Ontario, Canada Copyright Gary Larsen 2015 Theory, Culture, and Politics M.A. Graduate Program September 2015 Abstract THE MATERIALITY & ONTOLOGY OF DIGITAL SUBJECTIVITY: GRIGORI “GRISHA” PERELMAN AS A CASE STUDY IN DIGITAL SUBJECTIVITY Gary Larsen New conditions of materiality are emerging from fundamental changes in our ontological order. Digital subjectivity represents an emergent mode of subjectivity that is the effect of a more profound ontological drift that has taken place, and this bears significant repercussions for the practice and understanding of the political. This thesis pivots around mathematician Grigori ‘Grisha’ Perelman, most famous for his refusal to accept numerous prestigious prizes resulting from his proof of the Poincaré conjecture. The thesis shows the Perelman affair to be a fascinating instance of the rise of digital subjectivity as it strives to actualize a new hegemonic order. By tracing first the production of aesthetic works that represent Grigori Perelman in legacy media, the thesis demonstrates that there is a cultural imperative to represent Perelman as an abject figure. Additionally, his peculiar abjection is seen to arise from a challenge to the order of materiality defended by those with a vested interest in maintaining the stability of a hegemony identified with the normative regulatory power of the heteronormative matrix sustaining social relations in late capitalism.

  • Group Knowledge and Mathematical Collaboration: a Philosophical Examination of the Classification of Finite Simple Groups
    Group Knowledge and Mathematical Collaboration: A Philosophical Examination of the Classification of Finite Simple Groups Joshua Habgood-Coote and Fenner Stanley Tanswell Forthcoming in Episteme, please refer to final version. Abstract In this paper we apply social epistemology to mathematical proofs and their role in mathematical knowledge. The most famous modern collaborative mathematical proof effort is the Classification of Finite Simple Groups. The history and sociology of this proof have been well-documented by Alma Steingart (2012), who highlights a number of surprising and unusual features of this collaborative endeavour that set it apart from smaller-scale pieces of mathematics. These features raise a number of interesting philosophical issues, but have received very little attention. In this paper, we will consider the philosophical tensions that Steingart uncovers, and use them to argue that the best account of the epistemic status of the Classification Theorem will be essentially and ineliminably social. This forms part of the broader argument that in order to understand mathematical proofs, we must appreciate their social aspects. 1 Introduction Popular conceptions of mathematics are gripped by the myth of the ‘lone genius’. This myth is inspired by famous figures like Andrew Wiles, Grigori Perelman, and Srinivasa Ramanujan whose individual efforts are taken to be both representative and exemplary. In this paper, we push back against this individualistic view of how mathematics is and should be practiced, examining the significance of social and group level features of mathematical practices. In particular, we will discuss the epistemology of mathematics, and argue that in order to understand mathematics and its epistemology, we need to pay attention to collaboration, group knowledge, and other social factors.

  • The Work of Terence Tao
    The work of Terence Tao Charles Fefferman Mathematics at the highest level has several flavors. On seeing it, one might say: (A) What amazing technical power! (B) What a grand synthesis! (C) How could anyone not have seen this before? (D) Where on earth did this come from? The work of Terence Tao encompasses all of the above. One cannot hope to capture its extraordinary range in a few pages. My goal here is simply to exhibit a few contributions by Tao and his collaborators, sufficient to produce all the reactions (A)...(D). I shall discuss the Kakeya problem, nonlinear Schrödinger equations and arithmetic progressions of primes. Let me start with a vignette from Tao’s work on the Kakeya problem, a beautiful and fundamental question at the intersection of geometry and combinatorics. I shall state the problem, comment briefly on its significance and history, and then single out my own personal favorite result, by Nets Katz and Tao. The original Kakeya problem was to determine the least possible area of a plane region inside which a needle of length 1 can be turned a full 360 degrees. Besicovitch and Pál showed that the area can be taken arbitrarily small. In its modern form, the Kakeya problem is to estimate the fractal dimension of a “Besicovitch set” E ⊂ Rn, i.e., a set containing line segments of length 1 in all directions. There are several relevant notions of “fractal dimension”. Here, let us use the Minkowski dimension, defined in terms of coverings of E by small balls of a fixed radius δ.

  • Fundamental Theorems in Mathematics
    SOME FUNDAMENTAL THEOREMS IN MATHEMATICS OLIVER KNILL Abstract. An expository hitchhikers guide to some theorems in mathematics. Criteria for the current list of 243 theorems are whether the result can be formulated elegantly, whether it is beautiful or useful and whether it could serve as a guide [6] without leading to panic. The order is not a ranking but ordered along a time-line when things were writ- ten down. Since [556] stated “a mathematical theorem only becomes beautiful if presented as a crown jewel within a context" we try sometimes to give some context. Of course, any such list of theorems is a matter of personal preferences, taste and limitations. The num- ber of theorems is arbitrary, the initial obvious goal was 42 but that number got eventually surpassed as it is hard to stop, once started. As a compensation, there are 42 “tweetable" theorems with included proofs. More comments on the choice of the theorems is included in an epilogue. For literature on general mathematics, see [193, 189, 29, 235, 254, 619, 412, 138], for history [217, 625, 376, 73, 46, 208, 379, 365, 690, 113, 618, 79, 259, 341], for popular, beautiful or elegant things [12, 529, 201, 182, 17, 672, 673, 44, 204, 190, 245, 446, 616, 303, 201, 2, 127, 146, 128, 502, 261, 172].
